Turn off laptop back light without keyboard in Windows 7
Volumouse, from NirSoft, can also change the brightness of the screen, along with of course changing the volume.
It's explained on this post: How To Dim or Increase The Brightness of Laptop or Notebook LCD Screen
You can also change the brightness using a slider with Desktop Lighter, but I don't know if it works with Windows 7:
I cannot test it as I don't have a laptop running Windows 7 but you could try Display Brightness Console. More info at the bottom of this page about the Display Brightness Gadget:
To use the console app, the following parameters are allowed:
DisplayBrightnessConsole.exe
This will return the current brightness level.
DisplayBrightnessConsole.exe -getlevels
This will return all possible brightness levels accepted by the display, separated by a new line.
DisplayBrightnessConsole.exe 20 (or some other brightness level number)
This will set the brightness level of the display to the parameter given, in this case, 20.

How do I turn off my laptop's back light using a shortcut, or a program in Windows 7?
I have a Gateway NV59 and can press Fn + F8 to blacken the screen. At night, while watching a movie on my other monitor, it is a pain to try and find the right keys as they are far apart and hard to see with my lights off. Since I like to always be efficient, I would like to use my mouse instead of go from mouse, to keyboard, to mouse again (to hit play).

Snark about 13 yearsEdited my post with yet one more tool :-) . If it works, you can create shortcuts to it with various brightness levels.
